reoaaar Application filed October To all whom it may concern:

Be it known that I, NArnw J. LLOYD, a citizen of the United States. residing at in the county of Silverbow and State of lrlontana have invented Certain new and useful llmprovemenf in Centrifugal Separators, of "which tliffillowing is a specification.

ll/fy invention relates to new and useful ilnprorements in separators and more par ticularly to centrifugal separators.

The primary object of the invention is the provision of a separator of simple construction which will efl'ectually separate the lighter from the heavier materials.

A further "object/ 0f the invention is the for regulating the dis charge.

A still further object is the construction of a separator which may be easily cleaned.

With these 'and other invention consists in the novel details 0 construction and arrangement of parts which will be more clearly understood from the following description and drawings, in which,

Figure 1 is a vertical section. Fig. is a. view in side elevation of the cap of the re Fig. 3 is a top plan view of Fig. l'is a view in side elevation of the body portion of the revolving howl. Fig. is a top plan view of the basin and discharge for heavy particles. Fig. 6 is a top plan view of the cover of the stationary casing, and Fig. 7 is a detail of the bushing.

lln the drawings, the numeral 1 indicates a. base which'may be secured to any suitable support and has a depending arm or bracket 2 having a vertical opening through the center thereof. A shoulder 3 is formed midway the ends of the vertical opening and a cap 4 is secured on theunderside of the bracket 2 5 and receives a ball bearing 6 upon which rests a reduced end 7 of a vertical shaft 8. Between the shoulder on the 'shaft 8 and the shoulder 3 is received a packing ring 9. The upper end of the shaft 8 is forked, the purpose of which will presently described and keyed upon the ft is a small pinion 1.0 which meshes with and is operated by a large pinion 11 which is driven through any suitable power.

rality of elongated openings 14, as clearly shown in Fig. 1 of the drawings. The casing 13 is provided at the top with a flange 15 having a plurality of vertical openings 16 therein. I

The numeral 17 indicates the body portion of a bowl having a downwardly extending member 18 provided on the end with a tongue adapted to be received in the forked end of the shaft 8. A cap 19 is received in the bottom of the base and has an extension entering the base and overlying the meeting ends of the extension 18 and shaft 8. bushing 20 is received between the lower end of the casing 13 and the extension on the cap 19. The body portion 17- of'the bowl is provided at the circumferentially spaced openings 21 and the top is threaded interiorly. A cap 22 having the downwardly extending ribs 23 formed integral therewith is received in the top of the body of the bowl 17 and the ribs 23 extend downward into the bowl. The cap is provided with the exterior threads 24 80 which engage the threads on the interior of/ the body of the bowl. This cap is also provided with a plurality of circumferentially spaced notches 25 which are adapted to be brought into registration with the openings 21 formed in the body of the bowl and entering the openings and notches are the bushings 26 having enlarged heads and central openings. The cap 22 is provided with the flared top, as shown at 27, the purpose of which will be presently described.

Secured on the top of the casing 13 is a cover formed in two sect'ons 28 and 29 as is more clearly shown in Fig. 6 ings. When brought together the two sections are secured by means of bolts passing through the flanges 30 and the cover is secured to the body of the casing by means of bolts passing through lugs 31 and through the openings 16 formed on the flange 15 of the casing. When the sections are brought together they form the central opening 32 and the sections are each provided interiorly with a flange 33 forming a concaved receptacle 34.- The section 29 is provided with a spout 35, as is clearly shown in Figs. 1 and This spout leads from the coneaved receptacle 3A formed in the 6 of the drawings.-

cover. The flared end bowl 17 extends parts are assembled.

27 of the cap of the The numeral 36 indicates an inlet pipe top with a plurality of of the draw-' over the flange 33 when the which extends through the opening 32 in the cover of the outer'bowl, through the cap of the bowl 1?, and to a point near the bottom of the bowl 17.

The bushings 26 are adapted to be provided with central openings of various diameters, whereby the separation of the heavier material from the lighter may be regulated. T

Mounted within the receptacle is a basin or lining 37 the lower end of which is bent .to form a channel 38 and the upper end of which is bent, as shown at 39, to closely fit and engage the wall of the receptacle and the cover therefor. One side of the basin or lining 37 is cut away and bent to form a spout -l0 which passes through one of the openings 14 in the casing 13.

aving fully described the detailed construction of my device it is thought that the operation will be clearly understood. The material to be. separated is fed through the supply pipe 36 and is deposited on the bottom of the inner bowl 1?. The bowl 1? is adapted to be rapidly rotated through means of the gears 10 and 11 and as it is rotated the heavier particles will be thrown by centrifugal force toward the sides of the bowl and will rise and be (lischarged through the openings in the bushings 26 and deposited in the basin 3? from which they are discharged through the spout 40. The lighter particles will follow the ribs 23 formed on the cap 92 and will be carried toward the center of the bowl 17 and rise througi the opening in the cap and over the flange 27. These lighter particles are deposited in the concaved receptacle or channel 34: and discharged through the spout By inserting hushmgs having openings of greater or less diameter the degree of separation may be regulated so as to discharge particles of greater or less weight therethrough.

have constructed a separator which may be used for separating various articles and more particularly ores. It can equally as well be used in the separation of milk or other material.

\Vhen it is desired to clean the separator the sectional cover on the casing 13 is removed and the inner bowl 17 can then be taken out. the cap removed and the inner bowl I? cleaned. The basin or lining 37 can also be readily moved for cleaning purposes. Having fully described the invention what claim as new and desire to secure by Letters Patent is:
